Abstract
The utility model aims to provide a motor suspension bracket positioning structure capable of reducing the assembly accumulated tolerance of a suspension bracket. In the above scheme, increase the round pin cover as location structure on the suspension support body, with the screw hole cooperation of motor assembly, guarantee the accurate positioning of suspension support body to reduce that the great hole round pin that the via hole brought floats, reduced the tolerance accumulation, guaranteed the installation accuracy, thereby the deviation of effective control suspension support and sub vehicle frame mounting point guarantees the loading gesture of motor area suspension support assembly.
Description
Technical Field
The utility model relates to the technical field of automobile suspension systems, in particular to a positioning structure of a motor suspension support.
Background
With the increasing global energy crisis and the increasing environmental pollution problem, pure electric vehicles or hybrid electric vehicles are more and more popular with consumers. The motor used as a power source or an assistant power source can generate torque toggle when being accelerated, the instantaneous torque impact is large, the vibration and impact are transmitted to the frame and then transmitted to the vehicle body and a cab, the fatigue damage of parts and the noise in the vehicle are caused, therefore, the motor is required to be arranged on the vehicle body through a suspension system, the weight of the motor is supported through the suspension system, and the limiting and vibration isolating effects are realized.
In the prior art, due to the lack of a positioning structure, a hole pin generated by assembly has large floating, and the assembly precision is poor, so that the deviation between the mounting point of the suspension bracket and the mounting point of the rear auxiliary frame is large; the motor belt suspension support assembly is installed on the auxiliary frame, and the deviation of the installation points of the suspension support and the auxiliary frame influences the attitude of the motor belt suspension support assembly after the motor belt suspension support assembly is installed on the vehicle, so that the position relation between the motor belt suspension support assembly and the exhaust pipe and the deflection angle of the axis of the transmission shaft are influenced. The existing suspension supports are not provided with positioning structures to be accurately positioned on the motor, and all the suspension supports are assembled through holes, so that tolerance accumulation is large after assembly, and the accuracy of mounting points of the suspension supports and the rear auxiliary frame cannot be well guaranteed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a motor suspension bracket positioning structure capable of reducing the assembly accumulated tolerance of a suspension bracket.
In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides a motor suspension support location structure, the one end of suspension support body is provided with sub vehicle frame mounting hole, and the other end is provided with a plurality of motor mounting holes, is provided with the cotter in the motor mounting hole, and the protruding suspension support body that stretches out of cotter sets up, and the cotter is inserted in the screw hole of motor assembly and is constituted location fit, and the bolt passes motor mounting hole, cotter, screw hole and with suspension support body and motor assembly fixed connection.
In the above scheme, increase the round pin cover as location structure on the suspension support body, with the screw hole cooperation of motor assembly, guarantee the accurate positioning of suspension support body to reduce that the great hole round pin that the via hole brought floats, reduced the tolerance accumulation, guaranteed the installation accuracy, thereby the deviation of effective control suspension support and sub vehicle frame mounting point guarantees the loading gesture of motor area suspension support assembly.

Detailed Description
As shown in fig. 1-5, in a positioning structure of a motor suspension bracket, an auxiliary frame mounting hole 11 is formed at one end of a suspension bracket body 10, a plurality of motor mounting holes 12 are formed at the other end of the suspension bracket body, a pin bush 13 is arranged in each motor mounting hole 12, the pin bush 13 protrudes out of the suspension bracket body 10, the pin bush 13 is inserted into a threaded hole 21 of a motor assembly 20 to form positioning fit, and a bolt a penetrates through each motor mounting hole 12, the pin bush 13 and the threaded hole 21 to fixedly connect the suspension bracket body 10 with the motor assembly 20. Increase cotter 13 on suspension support body 10 as location structure, with the screw hole cooperation of motor assembly 20, guarantee the accurate positioning of suspension support body 10 to reduce the great hole round pin that the via hole brought and float, reduced the tolerance accumulation, guaranteed the installation accuracy, thereby the deviation of effective control suspension support body 10 and sub vehicle frame mounting point guarantees the loading gesture of motor area suspension support assembly.
Further, two cotters 13 set up respectively on two motor mounting holes 12 of tip and middle part, and the major diameter countersunk head portion of two screw holes 21 that correspond with these two cotters 13 is a circular port, another is the bar hole, and the length direction in bar hole is parallel with middle motor mounting hole 12 and 11 hole core connecting lines in sub vehicle frame mounting hole for adjust the surplus.
