Description

Servant brake crank throw before the battery-driven car

Technical field:

Servant brake relates to crank throw and uses the stop crank throw of line of drum lock before the battery-driven car on the servant brake before the utility model battery-driven car.

Background technology:

At present, the crank throw that on the battery-driven car servant brake, uses, its crank throw one side is installed on the camshaft of servant brake, and the opposite side of crank throw then installs the tight rope screw additional and fixes and regulate the line of stopping, and for using the drum lock line of stopping, the structure of above-mentioned servant brake crank throw is just inapplicable.In order on the crank throw of servant brake, also to use the bulging lock line of stopping, then should design a kind of crank throw of novel structure, the one end is installed on the servant brake camshaft, and the stop cylindrical registration mast of line of bulging lock can be installed at its other end, can satisfy the crank throw of said structure requirement, then servant brake just goes for the drum lock and has stopped line.

Summary of the invention:

The purpose of this utility model provides the preceding servant brake crank throw of a kind of battery-driven car, crank throw body plane plate one end of its crank throw is installed the disk plate by shaping curved slab and the camshaft that has the camshaft mounting hole and is connected, the crank throw body plane plate other end has the line registration mast upper grooves of stopping, and is connected with the line registration mast lower recess flat board of stopping by the arc transition bending plate.

Servant brake crank throw before a kind of battery-driven car, crank throw (1) is by crank throw body plane plate (5), shaping curved slab (7), camshaft is installed disk plate (3), the line registration mast upper grooves (6) of stopping, the arc transition bending plate (8) and the line registration mast lower recess flat board (9) of stopping constitute single piece, it is characterized in that crank throw body plane plate (5) one ends are connected by shaping curved slab (7) and camshaft installation disk plate (3), crank throw body plane plate (5) other end has the line registration mast upper grooves (6) of stopping, and is connected with the line registration mast lower recess flat board (9) of stopping by arc transition bending plate (8); On camshaft installation disk plate (3), have camshaft mounting hole (2).

Servant brake can satisfy following requirement with the planform of crank throw before this battery-driven car:

1, this crank throw one end can be installed the servant brake camshaft.

2, this crank throw other end can be installed the drum lock line registration mast of stopping.

3, this crank throw has certain intensity and suitable setting height(from bottom).

Servant brake is described as follows with the planform of crank throw before this battery-driven car:

Servant brake is formed by the steel plate Punching Technology with crank throw before this battery-driven car, shown in each accompanying drawing, servant brake is installed on the camshaft of servant brake with the camshaft mounting hole of crank throw before this battery-driven car, and the line registration mast of stopping is installed in stop the line registration mast upper grooves and the lower recess of the crank throw other end, when the servant brake on the battery-driven car front-wheel is braked, the line of then stopping spurs the line registration mast of stopping, and makes the line registration mast of stopping drive crank throw and rotates counterclockwise, and front-wheel is braked; When the releasing of brake handgrip, then crank throw is done the cw revolution and is resetted under the elastic force that is installed in the retracing spring on the line of stopping.

The line registration mast of stopping is a cylindrical shape, laterally vertically have the round tube hole that installs the line of stopping at registration mast cylinder middle part, the line registration mast of stopping is installed in stop the line registration mast upper grooves and the lower recess of this crank throw vertically, line one end of stopping is installed in the line round tube hole of stopping of registration mast, and be screwed, the line other end of stopping passes the spatial joint clearance between line registration mast upper grooves and the lower recess stopped of this crank throw, is installed on the brake lever of battery-driven car.

Servant brake is connected with cam installation disk plate by the shaping curved slab arc transition ground that is the arc surface bending downwards with crank throw body plane plate one end of crank throw before this battery-driven car, the disk plate is installed a location setting height(from bottom) is arranged to guarantee camshaft, on camshaft installation disk plate, have the camshaft mounting hole, be used for installing camshaft; The crank throw body plane plate other end at above-mentioned crank throw has the line registration mast upper grooves of stopping, and the line registration mast upper grooves of stopping is connected with the line registration mast lower recess flat board of stopping by the arc transition bending plate; The upwards reinforced rib of evagination is arranged on above-mentioned crank throw body plane plate, certain intensity is arranged to guarantee this crank throw.

Servant brake with the advantage of crank throw is before this battery-driven car: this crank throw both can be installed on the camshaft of servant brake, can the line registration mast of stopping be installed on crank throw again, used the bulging lock line of stopping, and this crank throw is simple in structure, and is easy to install.After assembling this crank throw, can make servant brake that bigger commonality is arranged, promptly also can use the bulging lock line of stopping.
