Description

Technical Field

[0001] The utility model relates to the technical field of hybrid vehicles, and in particular to a high-power range extender suspension mounting bracket. Background Art

[0002] As one of the current mainstream hybrid routes, the range extender is suitable for use on hybrid chassis, especially heavy vehicles with high-power range extender systems. The range extender system, together with the power battery, serves as the energy source of the chassis to provide power to the high-voltage drive components of the chassis, and has functions such as power generation and energy recovery (power consumption).

[0003] Conventional range-extending suspensions are installed with front and rear brackets + auxiliary suspension brackets, and then installed on the vehicle frame. For vehicles equipped with high-power range-extending systems, additional crossbeams for auxiliary generator support and suspension cushions are required, which is not friendly to weight and cost. After adding auxiliary generator support to the high-power range-extending system, the system as a whole has the risk of over-constraint, which reduces the reliability of the connection between the diesel engine housing and the motor housing of the range-extending system.

[0004] The prior art, application number 202011175274.6, patent name is a chassis structure of a range-extended hybrid vehicle and its installation method, including a body longitudinal beam, an engine, a range-extended drive module, a charging port, a battery, a distribution box, a service brake gas tank, a battery pack, a transmission shaft, a rear drive axle, a fuel tank and a vehicle controller, by mechanically connecting the engine and the range-extended drive module into a power drive unit, the power drive unit is arranged at the front of the vehicle; an integrated range-extended power drive system is adopted, which is small in size and light in weight, and the relative positions of the various parts are fixed and the space is compact, so that the position arrangement of each component and the axle load distribution are uniform, avoiding interference between the various systems; effectively reducing the transmission chain, reducing the weight and cost of the powertrain, and improving the transmission efficiency of the powertrain; at the same time, the generator, drive motor, motor controller, battery pack, and charging port are all compactly arranged, shortening the layout length of the wiring harness and reducing the cost. The above-mentioned prior art has too long front and rear overhangs, which is not friendly to the reliability of the connection between the engine and the generator. Utility Model Content

[0005] In view of the above problems, the utility model provides a high-power range extender suspension mounting bracket. Based on the range extender type that considers the high integration of the diesel engine and the generator (eliminating the traditional transition connectors such as shock absorbers and flywheels), the utility model designs an integrated high-power range extender suspension mounting bracket by evaluating the overall strength of the diesel engine flywheel housing and the motor housing. At the same time, the structure of the appearance is optimized, and corresponding weight-reducing holes are set. While ensuring the strength of the suspension mounting bracket, the overall weight of the suspension mounting bracket is reduced. This type of suspension mounting bracket can solve the auxiliary support problem of the rear-end generator of the high-power range extender, ensure the reliable installation of the overall system, solve the over-constraint problem caused by adding auxiliary support, and the assembly is simple and efficient.
