The comb-tooth type carrier is divided into a fixed comb-tooth type carrier and a telescopic comb-tooth type carrier, the main difference between the fixed comb-tooth type carrier and the telescopic comb-tooth type carrier is that a lifting comb-tooth frame of the fixed comb-tooth type carrier cannot transversely stretch and retract, the width dimension of the lifting comb-tooth frame is fixed, the lifting comb-tooth frame of the telescopic comb-tooth type carrier can transversely stretch and retract, and the width dimension of the lifting comb-tooth frame can be changed. Therefore, compared with the fixed comb-tooth type carrier, the telescopic comb-tooth type carrier can be suitable for vehicles of more different types, and the vehicle storing and taking process is more convenient.

main beams

2311, 2321 can be pushed to extend or retract in the vehicle width direction along the corresponding guide rail grooves by the cooperation of the power gear 213 and the two

racks

214, 215.

comb brackets

2311 and 2321, and the power gears of the two rack assemblies are connected to the output shaft of the motor 211 through the synchronizing assembly 24.

Specifically, as shown in fig. 8, the synchronizing assembly 24 includes two transmission gears 241, two tension pulleys 242, one driving gear 243, a synchronizing chain 244, and a tension link 245. One of the driving gears 241 is coaxially connected with the power gear 213 of one rack assembly, and the other driving gear 241 is coaxially connected with the power gear 213 of the other rack assembly. The driving gear 243 is sleeved on the output shaft of the motor 211, one tension wheel 242 is located between one transmission gear 241 and the driving gear 243, the other tension wheel 242 is located between the other transmission gear 241 and the driving gear 243, one end of the synchronous chain 244 is fixed on the tension connecting piece 245, and the other end of the synchronous chain 244 is fixed on the tension connecting piece 245 after sequentially passing around the transmission gear 241, one tension wheel 242, the driving gear 243, the other tension wheel 242 and the other transmission gear 241.

Of course, in other embodiments, the two rack assemblies in the comb teeth part of the rear wheel can be driven by different motors, and at this time, the power gear in each rack assembly is correspondingly connected with the output shaft of one motor, so that the main beams of the two comb teeth supports are pushed to slide along the guide rail groove under the driving of the corresponding motor.

The structure of the front wheel comb tooth subsection 12 is similar to that of the rear wheel comb tooth subsection 13, and the main difference is that only two comb tooth rods are arranged on each comb tooth support in the front wheel comb tooth subsection 12, and the number of the rack assemblies in the driving mechanism of the front wheel comb tooth subsection 12 is one.

In one implementation, as shown in fig. 9, the driving mechanism of the front wheel comb-tooth section 12 includes a driving gear 313, a transmission gear 314, a tension wheel 315, and a synchronization chain 316 in addition to the motor 311 and the rack assembly 312.
