Problems solved by technology
[0004] Pneumatic source brake: add an air compressor to supply the air source, which is noisy, wastes energy, and has poor reliability;
[0005] Hydraulic source brake: oil should be delivered by manual foot pedal, and hydraulic parts and oil pipes are easy to damage and oil leakage;
[0006] Electromagnetic brakes; the brake parts are easily damaged, the torque is insufficient, and the reliability is worse

Embodiment Construction
[0014] See figure 1 , figure 2 , which includes a brake stator 1 and a brake rotor 2. The inner surface of the brake stator 1 is evenly distributed with roller grooves 3 whose width transitions from the middle to both sides. Rollers 5 are evenly distributed in the circumferential direction, and the brake stator 1 is set on the outer ring surface formed by the combination of the rollers 5, and the outer end surface of each roller 5 is located in the corresponding roller groove 3, and the brake rotor 2 There is a center hole 6 with a keyway in the center of the center hole 6, and a roller shaft 8 with a key 7 is set inside the center hole 6 with a keyway. One side of the brake stator 1 is evenly distributed with fixing holes 9, and the test bench base 10 passes through the connecting rod 11 Inserted in the fixed hole 9, the claw 4 is externally connected with a lever 12, the test stand base 10 is set on the roller shaft 8 through the bearing 14, the output end of the roller sh...

The invention provides a brake structure for an entire detection device of a taximeter. The brake structure is rational, free from an external force source, durable, safe and reliable. The brake structure comprises a brake stator and a brake rotor, and is characterized in that pin roller grooves are uniformly distributed in the inner lateral surface of the brake stator, and the widths of the pin roller grooves are transited from a middle part to two sides; a pusher dog is sleeved on the outer peripheral surface of the brake rotor; pin rollers are uniformly embedded in the circumferential direction of the pusher dog; the brake stator is sleeved on an outer anchor ring formed by the combination of the pin rollers; the outer end face of each pin roller is positioned in the corresponding pin roller groove; a center hole with a key groove is reserved in the center of the brake rotor; a roller shaft with a key is sleeved in the center hole with the key groove; fixing holes are uniformly distributed in one lateral surface of the brake stator; a detection table pedestal is spliced into the fixing holes through connecting rods; the pusher dog is externally connected with a driving lever; the detection table pedestal is sleeved on the roller shaft through a bearing; and a roller is sleeved at the output end of the roller shaft.
Description
technical field [0001] The invention relates to the technical field of a vehicle verification device for a taxi meter, in particular to a brake structure of the vehicle verification device for a taxi meter. Background technique [0002] When we verify the taxi meter, we need to carry out the whole vehicle inspection on the taxi. When the inspected vehicle goes online for inspection or completes the inspection and drives out of the inspection line, if the inspection station at this time does not have a reliable brake device, the vehicle will not be able to move smoothly. On-line verification or off-line detection. [0003] At present, the most used brakes are pneumatic source brakes, hydraulic source brakes and electromagnetic brakes, all of which have different degrees of deficiencies in reliability. [0004] Pneumatic source brake: add an air compressor to supply the air source, which is noisy, wastes energy, and has poor reliability; [0005] Hydraulic source brake: oil ...
