Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and more specifically to a rear tie rod bracket assembly for an automotive powertrain. Background Technology

[0002] The main function of the rear tie rod assembly in an automotive powertrain system is to control the movement and torsional angle of the powertrain, thereby reducing vibration and noise in the vehicle body. One end of the rear tie rod assembly is connected to the subframe body, and the other end is connected to the automotive powertrain via a tie rod bracket.

[0003] Existing automotive powertrain rear tie rod bracket assemblies include a transmission connection bracket and a body bracket. The body bracket and the transmission bracket are connected to each other by bolts. In order to increase strength, the body bracket of the existing rear tie rod bracket is relatively thick, making the assembly appear bulky, increasing the difficulty of assembly, and also increasing the weight of the vehicle. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a rear tie rod bracket assembly for an automotive powertrain. This rear tie rod bracket assembly can reduce the weight of the vehicle body bracket without reducing strength, thereby reducing the difficulty of assembly and effectively reducing the weight of the vehicle body.

[0005] The technical solution of this utility model is to provide an automotive powertrain rear tie rod bracket assembly with the following structure: a transmission connecting bracket and a body bracket; one end of the body bracket is provided with a mounting groove, and two opposite sidewalls of the mounting groove are provided with through holes; a connecting post is provided on the sidewall of the one end of the body bracket, and the connecting post is provided with a threaded hole, which communicates with the through hole on one side of the mounting groove; one end of the transmission connecting bracket is embedded in the mounting groove, and a screw passes through the through holes on both sides of the mounting groove and one end of the transmission connecting bracket and is screwed into the threaded hole.

[0006] With the above structure, the automotive powertrain rear tie rod bracket assembly of this utility model has the following advantages compared with the prior art:

[0007] Because the rear tie rod bracket assembly of the automotive powertrain of this utility model has a connecting post on the side wall of one end of the body bracket, and the screw passes through the through holes on both sides of the mounting groove and one end of the gearbox connecting bracket and is screwed into the threaded hole of the connecting post, the structure of the connecting post ensures the strength of the screw connection, while also reducing the width of the body bracket, which can make the body bracket lighter, thereby reducing the difficulty of assembly and effectively reducing the weight of the vehicle body.

[0008] As an improvement, one end of the gearbox connecting bracket is provided with a mounting hole, and a bushing is provided inside the mounting hole. The screw passes through the bushing hole of the bushing. Both ends of the bushing protrude outside the two ends of the mounting hole, and the two ends of the bushing respectively abut against the inner walls on both sides of the mounting groove. With this structure, by setting a bushing on the gearbox connecting bracket and connecting it with the body bracket, a vibration reduction effect can be achieved.

[0009] As an improvement, a vibration damping component is provided at the other end of the vehicle frame bracket. This component includes a main spring and an inner core. The vehicle frame bracket has a connecting hole, with the main spring located within the connecting hole and the inner core located within the main spring. The outer side of the main spring is vulcanized and fixed to the inner wall of the connecting hole, and the inner side of the main spring is vulcanized and fixed to the outer wall of the inner core. The inner core has a frame connecting hole. With this structure, by incorporating the vibration damping component, the inner core is connected to the frame during assembly, and the component effectively reduces vibration.

[0010] As an improvement, the inner core has a trapezoidal structure with at least one openwork section. This structure provides better support and effectively increases strength.

[0011] As an improvement, the width of the side of the vehicle body bracket equipped with the vibration damping component is greater than the width of the side of the vehicle body bracket equipped with the mounting groove. This structure results in a vehicle body bracket with better strength and lighter weight.

[0012] As an improvement, the vehicle body support has at least one opening. This structure further reduces weight.

[0013] As an improvement, the main spring includes a connecting part and a supporting part; there are two connecting parts, each located between the two sides of the inner core and the inner wall of the connecting hole; there are two supporting parts, each located between the two ends of the inner core and the inner wall of the connecting hole. With this structure, the vehicle body bracket is more reliable.

[0014] As an improvement, the support portion includes a first support bar and a second support bar. The first support bar is arc-shaped, with both ends fixedly connected to the inner wall of the connecting hole, and the protruding part of the first support bar fixedly connected to the small end of the inner core. The two ends of the second support bar are fixedly connected to the inner wall of the connecting hole, and a recessed portion is provided in the middle of the second support bar, with the large end of the inner core embedded and fixedly connected to the recessed portion. With this structure, the first and second support bars support the two ends of the inner core respectively, resulting in better support of the inner core by the main spring.
