Example Embodiment

[0032] Example one

[0033] The wheel drive device of this embodiment is such as figure 2 As shown, the wheel frame 4 is fixed on the vehicle body, and the traction motor 2 mounted on the outer side determines the axis of rotation. The inner output end of the motor 2 is drivingly connected to the torsion tube 6 supported in the wheel frame 4 through the gear device 3. Therefore, the high-speed torque output by the traction motor 2 can be transmitted to the torque tube 6 through the gear device 3 after speed reduction and torque increase. The flange at the outer end of the torsion tube 6 and the inner end of the hub 9 mounted outside the motor housing through inner and outer bearings 7, 10 are fixedly connected by fasteners, and the outer end of the motor 2 is connected to the wheel frame 4 through the brake device 1, and The outer end of the hub 9 is connected to form an outer sealing device. The brake device 1 is composed of a brake caliper and a brake disc. The brake caliper i...

Example Embodiment

[0040] Example two

[0041] The wheel drive device of this embodiment is such as image 3 As shown, the basic structure is the same as that of the first embodiment. The difference is that a perforated inner retaining wall 5-2 extends near the outer end of the inner rim 5 toward the axis of rotation, and the inner end of the hub 9 has a flange 9-2 ', the outer end surface of the flange flanging 9-2' is attached to the inner end surface of the inner baffle wall 5-2, and a fastening structure is formed by the bolts and nuts worn. The inner end of the outer rim 12 extends toward the axis of rotation, and a perforated inner retaining ring 12-2 is attached to the outer end surface of the threaded hole of the hub 9, and the bolt passes through the perforation of the inner retaining ring 12-2 and the perforation of the outer sealing device at the same time. , The threaded holes screwed into the periphery of the outer end surface of the hub 9 form a pressing and fastening structure and a ...

Example Embodiment

[0046] Example three

[0047] The wheel drive device of this embodiment is such as Figure 4 As shown, the basic structure is the same as that of the first embodiment, and the outer end of the inner rim 5 has a wedge-shaped constriction 5-1, and the inner end of the hub 9 has a radially extending edge 9-3 on the side that matches the wedge-shaped constriction 5-1. Wedge-shaped stop 9-1, the inner end of the outer rim 12 has a wedge-shaped constriction 12-1, the outer end of the hub 9 is equipped with a hypotenuse wedge ring 11', the hypotenuse wedge ring 11' has a wedge shape with the inner end of the outer rim 12 A wedge-shaped inclined surface that matches the neck 12-1; the significant difference is: the outer end of the hypotenuse wedge ring 11' has a reduced diameter stop 11-2 that presses the outer end of the hub 9, and the inner end of the hypotenuse extends beyond the hub to be inserted into the hub 9 and the outer rim 12 radially spaced wedge plug 11-1. The wedge-shaped...

Abstract

The invention relates to a wheel rim driving device, and belongs to the technical field of engineering machinery transmission. The device includes a motor which is mounted on the outer side of a wheelframe to determine a spin axis, the inner output end of the motor is connected with a torque tube supported on the wheel frame through a gear device, the torque tube is fixedly connected with the inner end of a wheel hub sleeving outside the motor, and the outer end of the motor is connected with the wheel frame through a braking device and connected with the outer end of the wheel hub to form anouter sealing device, wherein the two ends of the wheel hub are fixedly connected with the outer end of an inner rim and the inner end of an outer rim in a sleeving mode correspondingly. Compared with the prior art, according to the wheel rim driving device, the wheel hub and the inner and outer rims are independently fastened and connected, the slip risk of the intermediate friction surface torsion is significantly lowered, stress when bolts are clamped, fastened and connected is only half the original, the stress condition is better, in addition, a hub adapter is reduced, and the structureis simpler.

Description

technical field [0001] The invention relates to a wheel side driving device, in particular to a wheel side driving device of an off-highway dump truck, relates to a brake, a motor and a connection method with the vehicle, and belongs to the technical field of construction machinery transmission. Background technique [0002] The non-highway dump wheel side drive device is installed inside the tire of the vehicle, and drives the vehicle forward by reducing speed and increasing torque. For example, on a mechanical dump truck, the wheel drive is at the end of the transmission chain, and its typical transmission route is that the power from the engine passes through the gearbox, and then passes through the final drive to the wheel drive. On the electric wheel dump truck, the typical transmission route is that the power from the engine is converted into electric energy through the generator, and then controlled by frequency conversion to provide driving force to the motor to driv...
