Problems solved by technology

[0003] 1. There are many transmission parts, so it is more complicated to manufacture and assemble, and its cost is higher
[0004] 2. The belt 12 will age after being used for a long time, and the tightness will be inconsistent, and its durability is poor
[0005] 3. Using this kind of electric brake actuator, it needs to cooperate with a caliper to carry out the overall design, so it is impossible to achieve a quick modification mechanism

Abstract

The invention discloses a driving device for parking brake of a vehicle. The driving device comprises a casing unit, a motor assembly and a speed reducing unit, wherein the casing unit comprises a ring gear around a first axis; the motor assembly comprises a motor and a worm extending along a second axis perpendicular to the first axis; the speed reducing unit is arranged in the casing unit and comprises a worm gear driving part, a planet carrier and a plurality of planet gears; the worm gear driving part is provided with a worm gear meshed with the worm, and a sun wheel which is arranged on the bottom side of the worm gear, extends along the first axis and is meshed with the planet gears; the planet carrier is provided with an input shaft which is connected to a clamping device and extends along the first axis; the motor can drive the worm to rotate so as to drive the worm gear driving part and the planet gears to rotate, and further the input shaft of the planet carrier is driven to rotate, and the clamping device is actuated to perform the parking brake action.

Description

Technical field [0001] The invention relates to a transmission device, in particular to a vehicle parking brake transmission device capable of driving a caliper. Background technique [0002] Refer to figure 1 , Is the "Electric Brake Actuator" of China Invention Patent Publication No. 101031459. This patent discloses the use of a transmission configuration of two pulleys 11 and a belt 12 to make a motor 13 run to drive a planetary gear mechanism 14 Running, and then drive a brake 15 to act. However, this kind of electric brake actuator has the following disadvantages: [0003] 1. There are many transmission parts, so it is more complicated in manufacturing and assembly, and its cost is higher. [0004] 2. The belt 12 will be aged for a long time, and the tightness will be inconsistent, and its durability will be poor. [0005] 3. With this kind of electric brake actuator, it needs to be matched with a caliper for overall design, so it cannot achieve a quick modification mechanism. ...
