Problems solved by technology

[0008] But for another problem, if one of the starter drive gears cannot engage the flywheel ring gear, the relay controlling the battery terminal of the electromagnetic switch will still work, and there will still be a large current flowing into the motors of each starter, so that each starter will Full power output, very prone to tooth milling or broken teeth

[0066] image 3 A circuit diagram of a first embodiment of the present invention is shown in . Parallel starting device among the figure has accumulator battery group 1 that is connected in parallel again after accumulator two in series, control switch 2 (is the key door switch in the present embodiment), two parallel starters 4 and 5 and a starter relay 3. The starter 4 includes a suction coil 47, a holding coil 48, a battery terminal 41, a switch terminal 42, a motor terminal 43, a machine terminal 44, a movable contact 46 and an electromagnetic switch 40 of two static contacts 45a, 45b, and a motor 49. The starter 5 includes a magnetic switch 50 with a suction coil 57, a holding coil 58, a battery terminal 51, a switch terminal 52, a motor terminal 53, a motor terminal 54, a movable contact 56 and two static contacts 55a, 55b, and a motor 59. The starter relay 3 includes a relay terminal 31, a coil 34, a movable contact 32 and two stationary contacts 33a and 33b.

[0072] see Figure 5 , Figure 5 Shown is a second embodiment of the patent of the invention. In this embodiment, the electromagnetic switch 50 of one of the parallel starters 5 only has switch terminals 52, battery terminals 51 and motor terminals 53, and no motor terminals 54 are provided. Other parts and circuits are the same as in the first embodiment.

[0073] The working process of the parallel starting device in this embodiment is the same as that in the first embodiment, and will not be repeated here.

[0074] The advantage of the second embodiment is that the parts used can be reduced and the stability of the whole system can be improved without affecting the system function.

[0076] see Image 6 , Image 6 Shown is the third embodiment of the patent of the present invention. In this embodiment, each starter in the parallel starting device is equipped with a starter relay, for example, the first starter relay 30a in the figure controls the starter 4, the second starter relay 30b controls the starter 5, and the first starter relay 30a The relay terminal 31 of the first starting relay 30b is connected in parallel with the relay terminal 31 of the second starting relay 30b, and the static contact 33a of the first starting relay 30a is also connected in parallel with the static contact 33a of the second starting relay 30b. During the starting process, each starting relay controls the electromagnetic switch corresponding to the starter. Other than that, the working process is the same as that of the first embodiment.

[0077] The advantage of the third embodiment is that it is not necessary to redesign the high-current relay, and it is beneficial to i...

Abstract

The invention provides a parallel connection starting device for starting an internal combustion engine, which comprises a storage battery, a control switch, at least two starters connected in parallel and at least one starting relay, wherein the starters respectively comprise electromagnetic switches and motors; main contacts of the electromagnetic switches of the starters connected in parallel are connected in series; the motors of the starters connected in parallel are connected in parallel; the starters connected in parallel work in the same time so as to start the engine; and large currents are led into the motors of the starters connected in parallel only after all the starters connected in parallel are meshed into gear rings. By adopting the parallel connection starting device provided by the invention, the large currents pass the motors of the starters only after all the starters connected in parallel are successfully meshed into the gear rings, so faults of tooth breakage or tooth milling of the starters, which are caused when certain starters in the parallel connection starting device are not meshed into the gear rings, can be avoided.

Description

technical field [0001] The invention relates to a starting device for an internal combustion engine, in particular to a parallel starting device for starting an internal combustion engine capable of starting an engine with a large displacement. Background technique [0002] A starter is a device used to start an internal combustion engine, but for a large engine with a displacement of tens of liters or even hundreds of liters, a single starter cannot provide sufficient starting power. At this time, two or more starters need to work at the same time. How to solve the problem of synchronous operation of two or more starters has become a key point in the design of parallel starters. [0003] see figure 1 , figure 1 It is a circuit diagram of a prior art parallel starter. The parallel starter device simply connects the switch terminals of the electromagnetic switches of two parallel starters together in parallel, and at the same time connects the two battery terminals togeth...
