Product Details
1. Basic Overview & Core Functional Positioning
The Z300-1001320CAA012702 Left AT Engine Cushion, also known as the left-side automatic transmission engine mount or engine rubber mounting pad, is a genuine OEM dedicated powertrain suspension component exclusively designed for the Zotye Z300 automatic transmission (AT) sedan series. Positioned on the left side of the vehicle’s engine bay, this specialized cushion acts as a critical elastic connection between the engine assembly, automatic transmission and vehicle chassis frame. It serves two irreplaceable core missions: firmly fixing the powertrain assembly in the standard position and isolating engine operating vibration and noise transmission to the vehicle body. As a key NVH (Noise, Vibration, Harshness) control part for Zotye Z300 AT models, it directly determines the stability of powertrain operation, driving smoothness and interior quietness during daily commuting, acceleration and idle cruising.
Different from universal MT engine cushions and right-side mounting pads, this left AT-specific cushion is professionally calibrated to match the weight distribution, torque output and vibration frequency characteristics of Zotye Z300’s automatic transmission powertrain system. Automatic transmission models generate different vibration amplitudes and stress distribution compared with manual transmission versions, requiring exclusive damping hardness and structural support parameters. During engine ignition, idle operation, rapid acceleration and gear shifting, the cushion effectively absorbs high-frequency vibration and instantaneous impact force generated by powertrain operation. It prevents rigid vibration conduction to the chassis, steering wheel and cockpit, eliminating abnormal jitter and resonance noise, and significantly improving overall riding comfort. Meanwhile, it limits excessive displacement and shaking of the engine and gearbox during driving, protecting peripheral oil pipelines, wiring harnesses and connecting parts from fatigue damage caused by long-term vibration.
The part number Z300-1001320CAA012702 represents a dedicated left-side AT exclusive specification for Zotye Z300, with unique mounting hole spacing, metal bracket size, rubber damping hardness and load-bearing parameters. It cannot be interchanged with manual transmission engine cushions, right-side mounts or engine cushions of other Zotye models such as Z500 and T600. Manufactured in strict accordance with automotive industry quality standards and Zotye original factory powertrain matching requirements, it features stable damping performance and precise assembly accuracy. Compared with inferior aftermarket cushions that suffer from rubber aging, insufficient support, vibration attenuation failure and easy deformation, the genuine Z300-1001320CAA012702 cushion maintains long-term stable powertrain support and vibration isolation effect, being the most reliable replacement part for Zotye Z300 AT model chassis maintenance.
2. Material Selection & Manufacturing Standards
The Z300-1001320CAA012702 Left AT Engine Cushion adopts a high-strength composite structure combining automotive-grade thickened metal bracket and high-elasticity modified rubber material, specially optimized for long-term powertrain heavy load, high-frequency vibration and complex engine bay environmental erosion. The outer fixing bracket is made of high-density stamped steel plate with integral bending and reinforcement processing, featuring ultra-high structural rigidity, compression resistance and tensile deformation resistance. It can stably bear the static weight and dynamic alternating load of the Zotye Z300 AT powertrain without bending, twisting or structural loosening, ensuring long-term firm support.
The internal damping rubber core uses high-quality oil-resistant, high-temperature resistant and anti-aging modified rubber raw materials, which are specially formulated to adapt to the harsh working environment of the engine bay. It maintains stable elasticity and damping performance in the extreme temperature range of -40°C to 130°C, avoiding softening failure under long-term engine high-temperature radiation or hardening and cracking in low-temperature environments. The material has excellent fatigue resistance, capable of withstanding millions of continuous vibration cycles without elastic attenuation, permanent collapse or structural pulverization. In addition, it features outstanding oil resistance and corrosion resistance, effectively resisting erosion from engine oil, coolant vapor and dust, preventing rubber aging and failure caused by long-term environmental corrosion.
All finished Z300-1001320CAA012702 engine cushions pass strict multi-process factory performance testing, including static load-bearing pressure testing, vibration fatigue durability testing, high and low temperature aging cycle testing, damping coefficient calibration and dimensional tolerance full inspection. The integrated vulcanization process ensures tight bonding between metal bracket and rubber core without delamination or gap. Strict quality screening eliminates defective products with uneven rubber density, loose bonding and insufficient load capacity, ensuring that every genuine cushion has consistent support strength, stable vibration absorption performance and ultra-long service life, fully meeting the long-term stable operation requirements of Zotye Z300 automatic transmission powertrain system.
3. Structural Composition & Working Principle
The Z300-1001320CAA012702 Left AT Engine Cushion adopts a mature integrated metal-rubber composite modular structure, which is the original standard matching structure for Zotye Z300 automatic transmission models. The overall structure is compact and highly targeted, mainly composed of high-rigidity metal fixing bracket, integrated reinforced base, high-elasticity vibration-damping rubber core, anti-tear protective rubber layer and standard assembly bolt holes. The overall size, mounting positioning and damping stroke are strictly calibrated according to the left-side assembly space and powertrain vibration characteristics of Z300 Z300 AT models, realizing zero-gap accurate assembly and perfect stress matching.
Its core working principle relies on rigid load-bearing support and elastic vibration energy absorption. The high-strength metal bracket undertakes the heavy-load fixing function, stably supporting the left side weight of the engine and automatic transmission assembly and limiting the overall displacement of the powertrain. The built-in high-elasticity rubber core serves as the vibration isolation buffer layer. When the engine operates, the generated vibration and instantaneous impact force are absorbed and decomposed by the rubber core through elastic compression and rebound deformation, converting mechanical vibration energy into internal friction energy for dissipation. This principle effectively cuts off the vibration transmission path from the powertrain to the chassis and cockpit, realizing dual effects of stable support and vibration noise reduction.
The optimized asymmetric damping structure is specially adapted to the unique vibration frequency of Z300 AT powertrain during gear shifting and acceleration. It provides soft buffer absorption for fine high-frequency vibration to improve driving smoothness, while offering strong rigid support for large displacement impact to prevent excessive powertrain shaking. The integrated anti-delamination vulcanization technology ensures that the rubber core and metal bracket are tightly combined without relative displacement during long-term vibration operation, avoiding local stress concentration and structural damage. Through scientific mechanical matching, it maintains the stable working posture of the powertrain and optimizes the overall chassis NVH performance of Zotye Z300 vehicles.
