The utility model overcomes the unable emergency braking's of traditional eccentric shaft problem that exists among the prior art. The utility model has the advantages of high safety, wide application range, long service life and the like.
Description
Technical Field
The utility model relates to an eccentric shaft field, more specifically say, relate to an eccentric shaft of electricelectric moves big bus car.
Background
At present, an eccentric shaft is disclosed in a Chinese patent net, publication No. CN208280997U, and belongs to the technical field of engines. The lift sensor solves the problem that the conventional lift sensor transmission pin pressed in the eccentric shaft is inconvenient to disassemble. The fixed orifices have been seted up on this eccentric shaft one end terminal surface, and the embedding has the driving pin in the fixed orifices, and the fixed orifices includes the erection segment and is located the inner spacing section of erection segment, the aperture of erection segment and the diameter looks adaptation of driving pin, and the aperture of erection segment is greater than the aperture of spacing section and makes and form spacing step between erection segment and the spacing section, and the tip of driving pin can support and lean on spacing step. The eccentric shaft has the advantage of conveniently disassembling the driving pin of the lift sensor.
Although the eccentric shaft in the above patent has the advantage of convenient disassembly, the eccentric shaft is not provided with a braking device, so that the eccentric shaft cannot be immediately stopped when emergency braking is needed in the use process.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an overcome the unable emergency braking's of traditional eccentric shaft problem that exists among the prior art, now provide the eccentric shaft of a pure electric bus car that has the emergency braking function.
The utility model discloses an eccentric shaft of electricelectric moves big bus car, include the disk body as the main part, the disk body openly go up eccentric department and be equipped with the connecting piece, the disk body back under eccentric department be equipped with the transmission shaft, the transmission shaft on be equipped with the brake disc, brake disc upper end be equipped with arresting gear.
During operation, the connecting piece is arranged at a required position, and then the transmission shaft is connected with a power source to start working. When emergency appears in work, the user can use the braking device to cut off the power transmission of the transmission shaft immediately, thereby improving the safety and the application range of the utility model.
Preferably, the braking device comprises a braking caliper body serving as a main body, the braking caliper body is a hydraulic cylinder body, an oil inlet is formed in the left end of the braking caliper body, symmetrically distributed pistons are arranged on the left side and the right side of the brake disc respectively, an oil seal baffle is arranged on the periphery of each piston, a steel sheet is installed at one end, close to the brake disc, of each piston, and a friction plate matched with the brake disc is arranged at one end, close to the brake disc, of each steel sheet.
During emergency braking, pour into hydraulic oil into the oil inlet, the piston draws close to the brake disc under the drive of oil pressure, and the friction disc that sets up on the piston can contact with the brake disc, stops the brake disc rotation at the combined action of oil pressure and friction disc, can stop the transmission shaft after the brake disc stall and rotate to realize emergency braking.
Preferably, the steel sheet is annular, the inner ring of the steel sheet is provided with at least 120 gear teeth, the diameter of the outer ring of the steel sheet is at least 873mm, and the diameter of the inner ring of the steel sheet is at least 712 mm; the friction plate is annular, the outer ring of the friction plate is provided with at least 128 gear teeth, the diameter of the outer ring of the friction plate is at least 902mm, and the diameter of the inner ring of the friction plate is at least 745 mm.
The static friction coefficient of the friction plate is 0.10-0.12, the dynamic friction coefficient of the friction plate is 0.08-0.09, and the maximum wear rate is 5 multiplied by 10-10 cm 3/J. The friction plate with the structure has the advantages of bearing high load, high wear resistance, long service life and the like.
The utility model has the advantages of high safety, wide application range and long service life.
