Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of electric tricycle rearmost axle pick-up unit, comprise supporting seat 10, carrier 20, motor control assembly 30 and brake gear 40, supporting seat 10 is welded to form by side arm 11, after-frame 12 and base 13, base 13 is symmetrical arranged the front roll 14 for supporting back axle 50 to be detected and back roll 15, front roll 14 and back roll 15 are fixed on base 13 by bearing seat 17; Carrier 20 comprises support board 21, and support board 21 front end is hinged on side arm 11, support board 21 is welded with two closed slides 22, and the leaf spring 23 for fixing back axle 50 to be detected is set in guide rail 22; Motor control assembly 30 is connected on the motor 51 of back axle 50 to be detected; Brake gear 40 is connected with front roll 14, and is placed on base 13.
Leaf spring 23 in the cofree movement of guide rail 22, thus can install the back axle of different size model.During detection, back axle to be detected 50 with motor 51 is fixed on leaf spring 23 by fixed parts such as U-bolt, nut and compressing tablets, and the wheel of back axle 50 to be detected is placed on front roll 14 and back roll 15, and can rotate relative to front roll 14 and back roll 15.During detection, carrier 20 is placed the weight of certain mass by testing requirements, be used for simulating the practical operation situation of back axle 50 to be detected when load; Control back axle 50 to be detected speed on demand by motor control assembly 30 to rotate; During operation, brake gear 40 applies different resistances can to front roll 14, and wheel can be made operationally to be obstructed, thus the state of real time modelling back axle when climbing.Motor control assembly 30 can control the motor 51 of different capacity, the operation conditions of convenient test back axle under the motor 51 of different capacity drives.
Preferably, motor control assembly 30 comprises power supply, fork shift handle 31, controller 32 and instrument, and fork shift handle 31 is located on side arm 11, and instrument is located on fork shift handle 31, controller 32 is arranged on base 13, and described fork shift handle 31, instrument, power supply are electrically connected with controller 32 respectively.During operation, turn fork shift handle 31, by circuit, signal is reached controller 32, controller 32 Received signal strength, judge the amplitude that fork shift handle 31 rotates, control motor 51 by different rotational speed, with Time Controller 32, rotating speed is presented in instrument in real time, operator according to the rotation amplitude of the speed adjustment fork shift handle 31 that instrument shows, thus can be easy to the speed adjusting back axle 50 to be detected in real time.
