Embodiment Construction
[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0033] Such as figure 1 , 2 , 4, 5, 6, 7, 8, and 9, the present invention has a bellcrank device for automatically adjusting the brake clearance function, including the active arm 7, the driven arm 2, and the limit block 14, the active arm and the driven arm Form a crutch. Both the driven arm and the driving arm are sleeved on the camshaft, the driven arm is fixedly connected with the camshaft, the driving arm is movably connected with the camshaft, and the driving arm can rotate around the camshaft. An adjustment screw 20 is arranged on the slave arm, and the adjustment screw is positioned on the slave arm and between the master arm and the slave arm. The active arm is provided with a ratchet mechanism 23, which is composed of a ratchet 19, a pawl rocker 5, and a ratchet 17. The ratchet can rotate on the active arm. The center of the ratch...

The invention discloses a crank throw device with the function of automatically adjusting a brake clearance. The crank throw device is characterized in that a driving arm and a driven arm form a crank throw, wherein the driving arm and the driven arm sleeve a camshaft; the driven arm is fixedly connected with the camshaft; the driving arm is movably connected with the camshaft and can rotate around the camshaft; an adjusting screw is arranged on the driven arm; a ratchet wheel mechanism consisting of a ratchet wheel and a pawl rocking bar is arranged on the driving arm; the ratchet wheel can be rotated on the driving arm; a thread hole is formed in the center of the ratchet wheel, and ratchets are arranged in the periphery of the ratchet wheel; the adjusting screw is spirally sleeved with the thread hole of the ratchet wheel; a pawl of the pawl rocking bar is kept in contact with the ratchets of the ratchet wheel under the effect of a spring; a limiting block is arranged on a hub gate cover and fits a head of the pawl rocking bar by the position. According to the crank throw device, the ratchet wheel structure is in match with the adjusting screw to automatically adjust a hub gate brake clearance; the crank throw device is simple in structure, small in size, low in processing cost, and reliable in action, and can be applied to hub gates of a non-motor vehicle, an electric vehicle and a motorcycle for automatically adjusting the brake clearance.
Description
technical field [0001] The invention relates to a bell crank for a hub brake used on bicycles, electric vehicles, tricycles and motorcycles, in particular to a bell crank device with the function of automatically adjusting the brake clearance (also known as the hub brake brake clearance automatic adjustment arm ). Background technique [0002] Brake slack automatic adjustment arms are widely used in the automotive field. But the automatic adjustment arm that the hub brake of bicycle, electric vehicle, tricycle and motorcycle is used yet does not yet have in the prior art at present. [0003] Automatically adjust the arm function: when the car is braking, it is realized by the friction force generated when the brake shoe and the brake hub are in contact. In the process of driving, frequent contact and friction between the brake shoe and the brake hub will cause the brake shoe to wear out, and the gap between the brake shoe and the brake drum will become larger, which will a...
