Description

Technical Field

[0001] The invention relates to the technical field of electric drive brake assemblies, and in particular to a parking module of a new energy electric drive assembly. Background Art

[0002] Parking brake types include disc integrated parking brake, drum integrated parking brake, etc. Most vehicles' parking brakes act on the rear axle, that is, on the two rear wheels. Among them, the parking brake mechanism of the drum integrated parking brake is simpler than that of the disc brake. The drum integrated parking brake only needs to convert the pulling into pushing the brake shoe to open. This mechanism is simpler and cheaper than the disc integrated parking brake. With the same torque, the diameter of the drum brake is smaller than that of the disc parking brake, and the drum brake has higher braking efficiency. Although the heat dissipation effect is average, the parking effect of the drum brake is better than that of the disc brake parking brake for static parking. For economical new energy vehicles, the drum parking brake has certain advantages due to its low cost. The existing drum parking brake shoe opening is generally driven by hydraulic pressure or reducer, and the shoe opening reaction speed is not high. Summary of the invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. By adjusting the spring setting, when parking, the driving mechanism drives the top ends of the two brake shoes to deviate from each other, and the brake shoes rotate outward around the shaft hole. When the driving mechanism is driven, the driving roller is driven to rotate forward. When the driving roller rotates forward, the limit rod is inserted into the spiral groove from the end ring groove at the top position, so that when the driving roller rotates forward, the moving seat is driven to move downward, and the moving seat pulls one end of the adjusting spring downward, so that the adjusting spring moves to the bottom of the line connecting the round rod and the shaft hole. Under the tension of the adjusting spring, the two brake shoes are pulled outward to deflect, so that the brake shoes and the brake drum are pressed together, and then the driving mechanism follows up to support and squeeze between the top ends of the two brake shoes, thereby improving the deflection reaction speed of the brake shoes;

[0022] 2. Through the setting of the driving mechanism, when the worm rotates, the worm drives the gear ring 1 to rotate through the bevel gear 3, the gear ring 1 drives the transmission gear 2 to rotate through the gear ring 2, and the transmission gear 2 drives the driving roller to rotate through the shaft rod 2, the bevel gear 4 and the bevel gear 5. When the driving roller rotates forward, it drives the moving seat to move downward until the gear ring 1 moves into the end ring groove at the bottom of the driving roller. The continued rotation of the driving roller does not drive the moving seat to move. When the driving roller is reversed, it drives the moving seat to move upward. Because the rotation speed of the driving roller driven by the driving motor is greater than the rotation speed of the shaft rod 1, the brake shoe can be opened at a faster speed when parking, thereby increasing the reverse speed of the brake shoe.
