Currently, pure electric fully loaded body technology has been incorporated into the bus products of numerous bus manufacturers. The chassis assembly process for fully loaded buses differs from that of traditional vehicles. The body and underframe must be assembled before chassis components are installed. Traditional hoisting methods are not suitable for the power motor assembly, which must be lifted from the bottom of the vehicle.

[0003] In the prior art, a method and tooling for assembling a full-load bus powertrain, such as patent number CN106672853A, employs a self-propelled and mechanized lifting method to place the full-load bus powertrain on a motor-driven assembly trolley platform. The self-propelled device then transports the full-load bus powertrain to the underside of the vehicle frame. A hydraulic lifting mechanism then lifts the full-load bus powertrain to the appropriate position. Hydraulically controlled lateral adjustment mechanisms and floating adjustment mechanisms precisely adjust the full-load bus powertrain to accurately connect and install it to the vehicle frame. The full-load bus powertrain assembly trolley of the present invention is battery-powered. After charging, the tooling can be controlled by a handle to achieve three-dimensional movements: vertical lifting, horizontal translation, and forward and backward movement. It can also perform floating fine-tuning of angles, facilitating positioning and adjustment during the assembly process. This tooling effectively solves the installation challenges of full-load plug-in bus powertrains and greatly improves installation efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] The embodiments of the present application provide a device and equipment for installing a full-load-bearing passenger car powertrain, which can solve the problem in the prior art that the height fine-tuning structure of this type of tooling is a floating adjustment mechanism. The main function of the floating adjustment mechanism is to rely on a telescopic cylinder to adjust the angle of the bracket for placing the powertrain. The accuracy of the height fine-tuning is not high, and there is a problem of reducing the accuracy of the height adjustment.

[0050] like Figure 1 、 Figure 2 and Figure 3 As shown, on the one hand, the present application provides a device for installing a full-load passenger car powertrain, which includes:

[0051] Installation platform 1;

Since the first lifting assembly 3 and the second lifting assembly 4 jointly adjust the placement height of the power assembly 5, the adjustment accuracy is higher through the threaded cooperation adjustment of the rotating part 41 and the linkage part 42 in the second lifting assembly 4, which facilitates small height adjustments, and solves the problem that the height fine-tuning structure of this type of tooling in the prior art is a floating adjustment mechanism. The main function of the floating adjustment mechanism is to rely on the telescopic cylinder to adjust the angle of the bracket for placing the power assembly, and the accuracy of the height fine-tuning is not high, which reduces the accuracy of the height adjustment.

When the rotating member 41 rotates, the driving component 423 is driven to move to adjust the distance between the upper connecting seat 421 and the lower connecting seat 422. The structure is simple and easy to manufacture.

[0062] In this example, the driving component 423 can be two spaced-apart sliders and a support link group arranged on the two sliders. The support link group includes two groups of cross-arranged support links, one end of the support link is hinged to the slider, and the other end is hinged to the upper connecting seat 421.

The two ends on the other side of the connecting rod 4231 are hinged to the upper connecting seat 421 or the lower connecting seat 422, and the connecting member 4232 is threadedly connected to the forward thread segment or the reverse thread segment. When the rotating member 41 rotates, the two connecting members 4232 approach or move away from each other to drive the corresponding connecting rod 4231 to move and adjust the distance between the upper connecting seat 421 and the lower connecting seat 422.

[0064] In this embodiment, the rotating member 41 is a rotating screw, and a forward thread segment and a reverse thread segment are provided on the rotating member 41 at intervals along the axial direction.

The structure is simple, easy to manufacture, and has a good driving effect.

[0065] In this example, the connecting rod 4231 includes two short connecting rods arranged at intervals and a support plate arranged between the two short connecting rods. The short connecting rods in the two groups of connecting rods 4231 are correspondingly hinged, and a connecting member 4232 is provided at the hinge.
