Detailed Description
In order to make the objects, technical solutions and advantageous effects of the present invention more clear, the following embodiments are combined to further explain the technical solutions of the present invention.
As shown in fig. 1 to 5, a novel linkage type braking structure comprises a frame chassis, a foot brake arm 1 is arranged on the frame chassis, the foot brake arm 1 is movably connected with the frame chassis, a limit is made by using an open pin to prevent the foot brake arm 1 from falling off, a pedal is arranged at the front end of the foot brake arm 1, and when an operator steps on the pedal, the foot brake arm 1 can move around the connection part with the frame chassis; the front end of the frame chassis is provided with a foot brake arm limiting rubber block 3, the foot brake arm 1 acts on the foot brake arm limiting rubber block 3, and the foot brake arm limiting rubber block 3 acts on the foot brake arm 1 to limit the foot brake arm 1 and prevent the foot brake arm from colliding with the frame chassis; the tail end of the foot brake arm 1 is movably connected with a foot brake linkage pull rod 9, and specifically, the foot brake linkage pull rod penetrates through a pin hole at the tail end of the foot brake arm 1 and is then installed at the head end of the foot brake linkage rod by a cotter pin for limiting, so as to prevent falling off; the tail end of a foot brake linkage pull rod 9 is connected with a right rear axle linkage pull rod 5 through a double-hole pin 8, the double-hole pin 8 is installed on a right brake conversion plate 11, the right brake conversion plate 11 is installed on a frame chassis through a rotating shaft 4, the brake conversion plate is fixed on the frame chassis through the rotating shaft 4, so that the brake conversion plate can flexibly rotate without clamping stagnation, the left end part of the right brake conversion plate 11 is connected with a left brake conversion plate 12 through a conversion linkage pull rod 10, and the conversion linkage pull rod 10 can swing left and right; the left brake conversion plate 12 is also installed on a chassis of the frame through a rotating shaft 4, the left brake conversion plate 12 and the right brake conversion plate 11 are identical in structure and are both ㄥ -shaped steel plates, the left end part of the left brake conversion plate 12 is movably connected with a left rear axle linkage pull rod 13, the left and right rear axle linkage pull rods are respectively and movably connected with a rear axle brake arm, the rear axle brake arm is movably connected with a rear axle brake drum, namely, the brake structure enables the left and right rear axle brake arms to simultaneously act through the swing of the conversion linkage pull rod 10, and further enables the rear axle brake drums on the left and right sides to simultaneously brake.
The action process is as follows: the foot steps on the brake arm, the brake arm rotates downwards, meanwhile, the brake arm pulls the foot brake linkage pull rod 9 forwards, the foot brake linkage pull rod 9 acts to further pull the right brake conversion sheet 11, so that the right brake conversion sheet 11 rotates around the rotating shaft 4, the right brake conversion sheet 11 rotates to drive the right rear axle linkage pull rod 5 to move forwards, and then the right rear axle brake arm 6 is pulled to act to rotate forwards, so that the right rear axle brake drum 7 generates brake force; meanwhile, the right brake conversion piece 11 is linked with the left brake conversion piece 12 through the conversion linkage pull rod 10, so that the left brake conversion piece 12 rotates around the rotating shaft 4, the left brake conversion piece 12 acts to drive the left rear axle brake arm 14 to act, and the left rear axle brake arm 14 rotates to enable the left rear axle brake drum 15 to generate brake force, so that the purpose of simultaneously generating brake on two sides is fulfilled.
When the left and right brake conversion pieces are processed, the fixing holes are arranged by using a die for blanking and forming, so that the double-hole pin 8 and the conversion linkage pull rod 10 which are used for connecting the foot brake linkage rod and the rear axle linkage rod are conveniently arranged in the die, and the brake conversion pieces are fixed on the rotating shaft 4 to rotate around the rotating shaft 4, so that the effect of linkage braking of the foot brake arm 1 is realized.
Other technical features than those described in the specification are known to those skilled in the art.
