Abstract
Disclosed by the utility model is a kind of electronic parking actuator, including babinet and upper cover, it is characterized in that, motor, transmission gear and output gear are equipped in the babinet, the babinet is equipped with motor location hole, gear locating shaft and output gear location hole successively according to the distribution of motor, transmission gear and output gear, motor shaft is stretched out in the motor top upwards across motor location hole, the motor shaft is equipped with motor gear, is driven by transmission gear between the motor gear and output gear.By the babinet centre-to-centre spacing that positioning transmission gear and output gear are driven simultaneously, reduces the accumulated error of multiple component cooperation, increase the positioning accuracy of transmission system, improve system noise, reduce the cost of assembly.
Description
Technical field
The utility model belongs to the technical field of Vehicle structure, is related to the braking system of vehicle, more specifically, this practicality
It is novel to be related to a kind of motor vehicle braking system electronic parking actuator.
Background technology
In the prior art, the electronic parking actuator of small-sized electric vehicle braking system includes shell, is set in the shell
There are motor and output gear, passes through Multi-stage transmission gear drive between the motor and output gear.In order to fix motor, it is arranged
One locating support is fixedly connected with shell, and the locating support and motor match setting, can improve the stability of motor.But
It is that the centre-to-centre spacing of transmission gear and output gear cannot be guaranteed, it is improper that gear will appear interference etc. in engagement process
Phenomena such as meshing state causes gear wear serious, and transmission efficiency reduces, and noise increases.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of electronic parking execution
Device reduces the accumulated error of multiple component cooperation by babinet while the centre-to-centre spacing of positioning multi-level column gear transmission, increases and passes
The positioning accuracy of dynamic system.
In order to solve above-mentioned purpose, the technical solution adopted in the utility model is：A kind of electronic parking actuator, including case
Body and upper cover, which is characterized in that motor, transmission gear and output gear are equipped in the babinet, the babinet is according to motor, biography
The distribution of moving gear and output gear is equipped with motor location hole, gear locating shaft and output gear location hole, the motor successively
Motor shaft is stretched out in top upwards across motor location hole, and the motor shaft is equipped with motor gear, the motor gear and output
It is driven by transmission gear between gear.
The transmission gear includes transmission gear A and transmission gear B, and the corresponding gear that is equipped with of the gear locating shaft positions
Axis A and gear locating shaft B, it is compact-sized using three-level column gear transmission, the body of actuator assembly can be reduced to greatest extent
Product.
The upper cover lower face is equipped with the boss for preventing gear from moving axially for compressing gear.
The boss is equipped with the groove being inserted into for gear positioning shaft head.
The utility model has the beneficial effects that：Pass through the babinet center that positioning transmission gear and output gear are driven simultaneously
Away from reducing the accumulated error of multiple component cooperation, increase the positioning accuracy of transmission system, improve system noise, reduce total
At cost.
Description of the drawings
Fig. 1 is the utility model general assembly drawing；
Fig. 2 is the utility model box structure diagram.
Specific implementation mode
As shown in Figure 1, a kind of electronic parking actuator, including babinet 1 and upper cover 2, babinet are equipped with one and accommodate motor body
Chamber, and sealed by housing plate, motor shock absorption pad 4 be equipped between 3 bottom end of motor and housing plate 5, play damping drop
The effect made an uproar.
Transmission gear 8 and output gear 7 are additionally provided in the babinet 1, as shown in Fig. 2, the babinet is according to motor 3, biography
The distribution of moving gear 8 and output gear 7 is equipped with motor location hole 6, gear locating shaft 10 and output gear location hole 11 successively.Electricity
3 top of machine passes through motor location hole 6 to stretch out motor shaft 31 upwards, and motor shaft 31 is equipped with motor gear 32,32 He of motor gear
It is driven by transmission gear 8 between output gear 7.
In the present embodiment, the transmission gear 8 includes transmission gear A 81 and transmission gear B 82, the gear positioning
Axis 10 is corresponding to be equipped with gear locating shaft A 101 and gear locating shaft B 102, gear locating shaft A 101 and gear locating shaft B
102 are respectively used to the position of positioning transmission gear A 81 and transmission gear B 82 so that transmission gear is placed on locating shaft and carries out
Stable rotation.
Output gear location hole 11 is used to position the position of output gear 7 so that output gear 7 is positioned embedded in output gear
Stable rotation is carried out in hole 11, the output end of output gear 7 is arranged downward, and babinet opposite position will be open setting, facilitate defeated
Go out gear output.
2 lower face of the upper cover is equipped with the boss for preventing gear from moving axially for compressing gear, and the boss includes supporting
The boss A 21 of pressure transmission gear A, it compresses the boss B 22 of transmission gear B and compresses the boss C 23 of output gear.It is described convex
Platform A 21 is equipped with the groove being inserted into for 101 heads gear locating shaft A, and the boss B 22 is equipped with for gear locating shaft B
The groove that 102 heads are inserted into, can improve the stability of gear locating shaft.
