Abstract

(57) [Summary] [Objective] The present invention allows a towed vehicle to run without imposing a burden on the engine of the towed vehicle. A transmission wire 8 for activating and connecting a transmission 11 and an engine 10 to a drive shaft 12 of a towed vehicle 2 to operate a control device 9 and a state sensing device for moving the transmission wire 8. When the traveling state is detected by (the connecting head 5 with the connecting pin 6 fixed), the power of the towing vehicle 1 is controlled by the control device 9 controlling the engine 10 and the transmission 11 by the switch and the back lamp power source attached to the towing vehicle 1. To make up for.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a towed vehicle provided with an engine, a drive unit, an engine control unit, a drive control unit, and a state detection unit.

[0002]

[Prior art]

 The towed vehicle had no engine or drive, and was pulled by the towed vehicle.

[0003]

[Problems to be solved by the device]

 The pulling force of the tow vehicle is compensated according to the strength of the pulling force of the towed vehicle, and multiple towed vehicles can be connected.

[0004]

[Means for Solving the Problems]

 According to the present invention, an engine, a drive unit, an engine control unit, a drive control unit, a state detection unit, and a transmission wire between the state detection unit and the control unit are attached to the towed vehicle to solve the insufficient force of the towing vehicle.

[0005]

[Action]

 Depending on the force of the towing vehicle pulling the towed vehicle, the state detection device attached to the towed vehicle's connecting pin pulls the amount, the wire is transmitted to the control device, the control device controls the accelerator of the engine, and the power of the engine is controlled. It is transmitted to the wheels through the drive.

[0006]

【Example】

 An embodiment will be described below with reference to the accompanying drawings and FIGS.

The state sensing device includes a connecting head 5 having slide guards 7c and 7d and a connecting pin 6 fixed therebetween (not shown in the drawing, but between the chassis frame 4a and the connecting head 5, the connecting head 5 and The connection head 5 is moved to the chassis frame 4a direction and the chassis frame 4b direction by a spring between the chassis frames 4b when the force is not applied.

The transmission wire 8 is attached to one side of the transmission wire 8 which can move together with the connecting head 5 and is connected to the control device 9 at the other side.

The control device 9 includes a control device for the engine 10 and a control device for the transmission 11.

The control device for the engine 10 controls the connecting head 5 to approach the chassis frame 4a when the towing vehicle 1 is accelerating forward or moving uphill, or when the towing vehicle 1 pulls the towed vehicle 2. The accelerator of the engine 10 is adjusted according to the pulling amount of 8 to reduce the load on the towing vehicle 1. Alternatively, when the towing vehicle 1 is accelerating backward or traveling backward on an uphill, when the towing vehicle 1 pushes the towed vehicle 2, the connecting head 5 approaches the chassis frame 4b and pushes the transmission wire 8 to the amount of the back lamp. By using the power source, the accelerator of the engine 10 is adjusted according to the amount to be pushed in the reverse direction when moving forward, so that the load on the towing vehicle 1 is reduced. Alternatively, the control device of the engine 10 is not operated by the switch and the exhaust brake switch attached to the towing vehicle 1 on the downhill. The engine 10 is started and stopped by a switch attached to the towing vehicle 1. (Each function of the control device 9 can use conventional technology and is not shown in the figure)

In the automatic transmission, the control device of the transmission 11 uses the power supply of the back lamp to switch between forward and reverse, and the switch attached to the towing vehicle 1 switches between neutral, forward and reverse. It has become.

The drive shaft 12 transmits the rotation of the transmission 11 to the differential 13.

The differential 13 transmits the rotation of the drive shaft 12 to the wheels 14.

The wheels 14 are driven by the rotation of the differential gear 13.

The present invention is not limited to the above-mentioned embodiment, and may be modified within a range not departing from the gist of the present invention.

[0016]

[Effect of device]

 As described above, the present invention is capable of accurately compensating the pulling force of the tow vehicle or connecting a plurality of towed vehicles with a simple structure, and the tow vehicle guides the towed vehicle from the role of the tow vehicle. The role changes as a dedicated car to guide and the operation becomes easier.
