Description

Technical Field

[0001] The utility model relates to the technical field of differential assembly, in particular to an adaptive angle correction mechanism for a differential. Background Art

[0002] The differential is a component of a car, a mechanism used to drive the left and right (or front and rear) drive wheels at different speeds. A commonly used differential consists primarily of left and right axle gears, two planetary gears, and a gear carrier. When a car is turning or driving on uneven surfaces, the differential enables the left and right wheels to roll at different speeds, ensuring that the drive wheels on both sides are in pure rolling motion. The differential is designed to adjust the speed difference between the left and right wheels. In four-wheel drive, all four wheels must be connected to drive them. If the four wheels were mechanically connected, the car would not rotate at the same speed when turning. To ensure that the car's rotation speed is roughly consistent when turning, a center differential is required to adjust the speed difference between the front and rear wheels.

[0003] During differential assembly, the planetary gear shaft assembly is crucial. If the hole in the differential housing that mates with the slotted shaft is not precisely positioned and is not aligned with the axis of the slotted shaft press head, press-fitting the slotted shaft will be difficult, making it difficult to guarantee a satisfactory assembly pass rate.

[0004] Therefore, how to provide an adaptive angle correction mechanism for a differential has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by the utility model is how to provide an adaptive angle correction mechanism for a differential.

[0006] To achieve the above-mentioned purpose, the utility model provides an adaptive angle correction mechanism for a differential, comprising: a transverse plate and an adjustment mechanism, wherein a pressure head mechanism for performing angle correction on the differential is arranged on the transverse plate, and the pressure head mechanism comprises a pressure head a and a pressure head b, which are arranged in parallel on the front side of the transverse plate, the cross section of the pressure head a is a cylindrical structure, and an opening is preset at the bottom of the pressure head a, and the cross section of the pressure head b is a conical structure.

[0007] The horizontal plate is used to provide fixed support for the pressure head mechanism, and pressure head a and pressure head b play a dual pressing and fixing role with the differential. Pressure head a presses and fixes the straight shaft on the differential, and the cylindrical structure of pressure head a cooperates with the preset opening at the bottom, so that pressure head a can adaptively correct the straight shaft on the differential. Pressure head b is used to press and fix the spring pin on the differential, realizing the double pressing and fixing function.

[0008] Preferably, the adjustment mechanism includes a support plate, a cylinder, a connecting block, a positioning block and a positioning rod;

[0009] The support plate is arranged parallel to the top of the horizontal plate;

[0010] The cylinder is vertically arranged on the top of the support plate, and the output shaft of the cylinder extends downward to the bottom of the support plate;

[0011] The connecting block is installed at the end of the output shaft of the cylinder, and one end of the connecting block is fixedly connected to the cross plate;

[0012] The positioning block is arranged on the rear surface of the horizontal plate;

[0013] The positioning rods are arranged on the support plate at equal intervals, and the positioning rods are arranged in a penetrating manner in the positioning blocks.

[0014] The support plate cooperates with the positioning rod to provide fixed support for the entire device. The cylinder adopts the existing structure on the market in this field. It drives the cross plate to move longitudinally up and down parallel through the connecting block. The positioning block and the positioning rod are slidingly connected. When the cross plate moves, it drives the positioning block to move along the positioning rod, thereby limiting the movement of the cross plate, so that the cross plate always moves within the preset range.

[0015] Preferably, a connector is installed at the end of the positioning rod, and the connector and the positioning rod are threadedly connected.

[0016] The positioning rod is installed at a designated location outside through the connector. The threaded connection design makes it easy for users to replace and maintain the connector regularly.

[0017] Preferably, the adjustment mechanism further includes an electric push rod and a mounting plate;

[0018] The electric push rod is arranged transversely on the front surface of the horizontal plate;

[0019] The mounting plate is slidably arranged on the front surface of the horizontal plate, and one end of the mounting plate is connected to the output shaft of the electric push rod, and the front surface of the mounting plate is connected with a pressure head a and a pressure head b.

[0020] The pressure heads a and b are arranged on the front surface of the mounting plate via a connecting rod, and the pressure heads a and b are detachably connected to the connecting rod. This method is common knowledge in this field, so it will not be repeated here. The electric push rod adopts the existing structure on the market, which is used to drive the pressure heads a and b to move horizontally and parallel to the left and right through the mounting plate, so as to move the pressure heads a and b to the specified position according to needs.

[0021] Preferably, a limit block is further included, which is arranged on the front surface of the transverse plate and located on the side of the mounting plate away from the electric push rod.

[0022] The design of the limit block limits the movement of the mounting plate, so that the mounting plate always moves within this plane.

[0023] The beneficial effects of the utility model are:

[0024] 1. When the present invention is in use, the pressure head a and the pressure head b and the differential play a dual pressing and fixing role, wherein the pressure head a presses and fixes the straight shaft on the differential, and the cylindrical structure of the pressure head a cooperates with the preset opening at the bottom, so that the pressure head a plays the function of adaptive angle correction for the straight shaft on the differential, and the pressure head b is used to press and fix the spring pin on the differential, realizing the dual pressing and fixing functions, reflecting the practicality of the present device.

[0025] 2. When the utility model is in use, the design of the adjustment mechanism makes it easy for the user to move the pressure head a and the pressure head b to the specified position according to actual needs, which not only avoids the limitations of the use of the device, but also improves the press-fitting efficiency of the differential to a certain extent, thereby facilitating its popularization and use.
