Vehicle gap adjustable conical brake device

Abstract

The invention relates to a vehicle gap adjustable conical brake device. The vehicle gap adjustable conical brake device comprises a barrel. The barrel is provided with a first end port and a second end port. A parking end cover is arranged in the first end port. A running end cover is arranged in the second end port. The parking end cover, the running end cover and the barrel define a cavity. A parking piston and a running piston are arranged in the cavity. One end of the parking piston can abut against the parking end cover, and the other end of the parking piston can abut against the running piston. The running piston can abut against the running end cover. A set of spring positioning grooves extending axially are evenly distributed in the parking piston. Parking springs are arranged in the spring positioning grooves and tightly abut against the parking end cover. The running piston is hollow, and a transmission shaft which is in sliding fit with the running piston is arranged in the hollow interior of the running piston. The vehicle gap adjustable conical brake device has the advantages that large brake torque can be achieved in a small mounting space, the brake effect is better, by adopting the nesting integral design of running and parking brakes, a parking brake does not need to be arranged independently, a vehicle frame space is saved, and great convenience is provided for overall vehicle arrangement.

Description

technical field

[0001] The invention relates to a brake device, in particular to a conical brake device with adjustable clearance for a vehicle, which belongs to the technical field of vehicle brake systems. Background technique

[0002] As far as the applicant knows, traditional automobiles and engineering vehicles mostly use caliper disc brakes or full-disk multi-plate wet brakes. Among them, caliper disc brakes are widely used and occupy most of the market due to their low price and relatively stable braking performance. However, the increase in size brings difficulties to the distribution of the installation space of the vehicle chassis, and the friction area of ​​the friction pair of the caliper disc brake is relatively small, the friction plate wears quickly, and the replacement cycle is short, resulting in an increase. Maintenance and use costs; the full-disk multi-disc wet brake has a long service life and strong adaptability to the environment. Its multi-disc struc...
