Advantage of the present utility model and good effect are: the utility model provides a kind of service brake arrangement for electro-tricycle of structure design advantages of simple, compared with existing service brake arrangement, the technical program structure is compacter, and consumptive material is less, reduces the productive costs of whole device; By adopt multiple be installed on same pedestal gear transmission moment and plectrum be set extend downwards, solve existing service brake arrangement to ensure the activity space of plectrum and the problem of riser length of having to strengthen, therefore whole device in height has less size, just not easily backing in the process that vehicle travels; Adopt the mode of gear transmission moment, the wearing and tearing between gear are less, solve the safety issue that between existing service brake arrangement mandrel and axle sleeve, serious wear is brought; The mode of meshed transmission gear makes trample action sensitiveer, and operator can complete braking without the need to great dynamics, large distance ground pushes pedals, can be set above-mentioned sensitivity by the gear combination matching different drive ratios and regulate.
Preferably: described pedestal is inverted U-shaped shape, is obtained by sheet metal bending forming, and the pedestal of each gear is established and is arranged between the front side plate of pedestal and rear quarter panel.
Preferably: the gear of multiple engaged transmission in turn comprises the second gear being positioned at the first anterior gear and being positioned at rear portion, and both direct engaged transmission, the lower end of support arm is connected with the first gear is affixed, and plectrum is affixed to be arranged on the second gear.
Preferably: the transmitting ratio of the first gear and the second gear is 2:3.
Preferably: between pedestal and the section bar of chassis of vehicle body, the lower end of support arm with between the gear of front portion, plectrum with between the gear at rear portion, all adopt that the mode of welding is affixed to be connected.
